BackgroundResearch productivity is critical to academic surgery and essential for advancing surgical knowledge and evidence-based practice. We aim to determine if surgeon affiliation with top US universities/hospitals (TOPS) is associated with increased research productivity measured by numbers of peer-reviewed publications in PubMed (PMIDs).MethodsA bibliometric analysis was performed for PMIDs. Affiliated authors who published in trauma surgery (TS), surgical critical care (SCC), acute care surgery (ACS), and emergency general surgery (EGS) were evaluated for publications between 2015 and 2019, and lifetime productivity. Our analysis included 3443 authors from 443 different institutions. Our main outcome was PMIDs of first author (FA) and senior author (SA) in each field (2015-2019) and total lifetime publications.ResultsSignificant differences exist between PMIDs from TOPS vs non-TOPS in FA-TS (1.34 vs 1.23, P = .001), SA-TS (1.71 vs 1.46, P < .001), total SA-PMIDs (44.10 vs 26.61, P < .001), and SA-lifetime PMIDs (90.55 vs 59.03, P < .001). There were no significant differences in PMIDs for FA or SA-SCC, FA or SA-ACS, FA or SA-EGS, FA-total PMIDs 2015-2019, or FA-lifetime PMIDs ( P > .05 for all).ConclusionThere were significantly higher TS PMIDs among FAs and SAs affiliated with top US institutions in 2015-2019, along with higher total PMIDs (2015-2019) and lifetime PMIDs. These findings are of significance to future graduate medical applicants and academic surgeons who need to make decisions about training and future career opportunities.

医院/大学隶属关系对美国作者在创伤、外科重症监护、急症护理和急诊普通外科领域的研究生产力的影响

背景研究生产力对于学术外科手术至关重要，对于推进外科知识和循证实践至关重要。我们的目的是确定外科医生与美国顶尖大学/医院 (TOPS) 的联系是否与提高研究生产力相关，而研究生产力是通过 PubMed (PMID) 中同行评审出版物的数量来衡量的。方法对 PMID 进行了文献计量分析。对在创伤外科 (TS)、外科重症监护 (SCC)、急症护理外科 (ACS) 和急诊普通外科 (EGS) 领域发表论文的附属作者在 2015 年至 2019 年间的发表论文以及终生生产力进行了评估。我们的分析包括来自 443 个不同机构的 3443 位作者。我们的主要成果是每个领域（2015-2019）的第一作者（FA）和高级作者（SA）的 PMID 以及总的终生出版物。结果FA-TS（1.34 vs 1.23，P = .001）、SA-TS（1.71 vs 1.46，P < .001）、总 SA-PMID（44.10 vs 26.61，P）中 TOPS 与非 TOPS 的 PMID 之间存在显着差异< .001) 和 SA 生命周期 PMID (90.55 vs 59.03, P < .001)。FA 或 SA-SCC、FA 或 SA-ACS、FA 或 SA-EGS、2015-2019 年 FA 总 PMID 或 FA 生命周期 PMID 的 PMID 没有显着差异（所有 P > .05）。结论2015-2019 年，美国顶尖机构附属的 FA 和 SA 的 TS PMID 显着升高，总 PMID（2015-2019 年）和终生 PMID 也更高。这些发现对于未来的研究生医学申请者和学术外科医生来说具有重要意义，他们需要就培训和未来的职业机会做出决定。
